HOUSING FOR ROLLING-MILLS.

No. 9o7,135.

Specification of Letters Patent.

Patented Dec. 22, 1908.

To all whom 'it may concem:

Be it known that I, SAMUEL E. DIESCHER, residing at Pittsburg. in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Housings for Rolling-Mills, of which improvements the following is a specification.

The invention described herein relates to certain improvements in mills for swagng billets.

It has heretofore been the practice to mount the swaging rolls in one air of housings and the pinions employed or transmitting the desired oscillatory movement to the swages, in another pair of housings. The thrust which the crank arms operated by the pinions exert on the crank-arms connected to the swages, exerts so great disturbng infiuence, that the maintenance of the proper relative position of the housings of the swages and pinions is a source of great expense and the cause of frequent interruptions in the operation of the mill.

The invention described herein consists in providing a housing with windows or o enngs for the recepton of the bearings o the rolls and pinions, so that said parts will be mounted in an integral structure.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part of the specification, Figure 1 is a side elevation of a housing embodying my improvement; Fig. 2 is a similar view illustratmg a modification of my invention, and Fig. 3 is a sectional plan view on a plane indicated by the line III-III Fig. 1.

In the practice of my invention, the housings 1 are made of suflicient width to permt of the formation of windows or openings 2 and 3 for the reception of the journal blocks 4 and 5 for the swages 6 and driving pinions 8. In the Construction shown in Fig. 1 the Windows are made sufficently wide to permit of the endwise insertion of the pinions and swages through them. If however the housings are constructed with a removable cap 9 as shown in Fig. 2, the windows need not be made of so great a width. Where the pinions 8 are driven by means of a pinion 10 of the power shaft, it is preferred that the' housings should be made su'ficently wide to permt of the formaton theren of a window or o ening 11 for the reception of the journal bicks 12 of said transmttng pinion 10. As the driving pinions should intermesh so as to insure synchronous movements of the swages, provision is made for the passage of the article operated on between the pinions by` cutting peripheral grooves 13 in the pinions, in the lne of feed of the article. It is preferred to also em loy a guiding tube 14, to prevent the article eing caught by the pinions. T he 'pinions have counterbalanced arms 15 secured on their journals, and the pins 16 on said arms are connected to pins 17 on counterbalanced arms 18 on the journals of the rolls. When the housings are constructedwith removable caps, the latter and the body of the housings are preferably constructed so as to interlock one with the other, thereby relieving the bolts 19 from transverse or shearing strains.

I claim herein as my invention:

Housings for rolls having windows or openings for the rolls' and drivng pinions formed in an integral structure in combination with rolls having their journals mounted in two of said windows, driving pinions having their journals mounted in the other windows and crank and pitmen connections from the pinions to the rolls.

In testimony whereof, I have hereunto set my hand.

SAMUEL E. DIESCHER.
